A filtering device for carrying out a filtering process in a space domain of image data derived from an external visual image input means and then delivering control information to a controlled driving device with the filtering device containing fundamental operator generation device for generating fundamental operators within the same fundamental operator series, and a filtering processing device for carrying out a convolution of a fundamental operator with an image data array and conducting a sequential series of such convolutions with varying input data based upon data detected at the output of the filter processing, so that the sequential convolution attains an effect equivalent to that attained by the direct convolution of the initial image data array with an expanded operator.
